Can vanadium also store hydrogen

Is vanadium a suitable material for hydrogen storage and permeation?

Vanadium and vanadium based alloys are extensively studied as a candidate material for hydrogen storage and permeation applications. The efforts were made to enhance the cyclic hydrogen storage capacity and prevent the pulverization. A large number of elements could form the alloy with vanadium in a wide range of concentrations.

What is the reversible hydrogen storage capacity of a vanadium based alloy?

Vanadium (V)-based alloys attract wide attention, owing to the total hydrogen storage capacity of 3.8 wt% and reversible capacity above 2.0 wt% at ambient conditions, surpassing the AB 5 -, AB 2 - and AB-type hydrogen storage alloys.

Are vanadium-based alloys suitable for hydrogen storage applications?

Vanadium-based alloys are potential materials for hydrogen storage applications in Remote Area Power Supply (RAPS) and Movable Power Supply (MPS). In this study, V 80 Ti 8 Cr 12 alloys are tailor-made to meet the RAPS and MPS working conditions (293–323 K and 0.2–2 MPa).

Does vanadium oxide affect hydrogen storage capacity?

However, all the samples used in this study showed rapid hydrogen absorption, suggesting that very little amount of vanadium oxide may not have a significant effect on the alloy's ability to store hydrogen. Hence, the lattice contraction could be the key factor affecting the hydrogen storage capacity.

Can a vanadium alloy reduce the cost of hydrogenation?

Vanadium alloys The addition of alloying elements has been found effective not only to reduce the cost but also to alter the hydrogenation properties such as dissociation pressure and hydrogen storage capacity.

Is vanadium a good hydride forming metal?

The metallic vanadium has an excellent hydrogen storage properties in comparison to other hydride forming metals such as titanium, uranium, and zirconium. The gravimetric storage capacity of vanadium is over 4 wt% which is even better than AB 2 and AB 5 alloys.
